all citizens o the United States, residing in the borough of Brooklyn,lsew "York cttw, in

the county o Kings and State of New i ark,

have invented certain new and useful lmprovements in Folding PaperBoxes, of which the following is a speeiiication.

This invention relates to folding paper boxes made ont of a blank havinga middle plain zone creased into panels to form the four sides of tbebox, am tivo parallel finale hesive tape, or bye pasted flap forming enextension of one of the end panels, or by some equivalent method; butthis makes a weak joint m a vulnerable place, and our invention has :forits object tu doau'ay with such a joint. We accomplish this by pro-Vriding a box wlxichlxas its joint at an interwith its ends united toform a tube.

" mediate line iu one of the side panels and the adjacent tiaps, and wealso provide an imrored form of joint for this location.

Fig. 2 represents a perspective vieu' of said blank Fig.3 represents'a similar view showin two of the flaps folded down tostartthe Lbottom closure. Fig. 4 represents a similar vieu' of the boxwith closed bottom and open top. Fig.

-5 represents a similar vieu showing the box completely closed. Fig. 6represents a plan view of a modified form of blank.

The blank shown in l? ig. 1 may be formed by any suitable method out ofmaterial such as straw-board, corrugated board, etc., in a single piececomprising;r a middle zone which consists of a line of intermediate fullpanels 10, 11, 12 and end artpanels 13, 14 to form the sides of the ox,together with two parallel marginal zones transversely slitted at'15. 15to form full flaps 16, 17, 1S and i part-ilaps 19, 20 contiguous to therespective pane s, for the. top and bottom closures of 7 sonner-ts resseBox.

Theheight o the panels 1G and 18 is preferably bali-tbe Width o tne panels11 and 13, le..v We also prefer to 'iorm the edge o one of thepart-panels, as 33, with recesses :23 and the edge of the other, is,with complemental projections 24 constituting a dove-tail orinterlocking joint. tvbcnthe blank ends are brought together. Inconstructing the box fromA the bis the latter is first. formed into alet tube by bringing its ends togetlier end interlocking the dove-tailsand t en pasting a suitable strip or tape, such as a cloth tape 25 overthe union. Fig. 2 shows this tube opened ont. into rectangular form.Since the joint. of this box occurs intermediate of one of the sidepanels and traverses both this panel and the adjacent a s it can be mademuch more secure and is ess vulnerable than the old forni of joint whichit was customary to make at one of the corners between adjacent sidepanels. 'With this old corner jointthe sealing tape or the extensionflap which united the panels could not. be extended bevond the upper andlower edges of these panels. and its ends were easilyv started, so thatthe joint was much inferior to our improved form and location of joint.It is to be noted. also that we retain the advantage of the oldconstruction which enables the blank to be formed into a tube by joiningits ends, and shipped lat in this doubled shape from the maker to theuser, which tended blank. bile a box-blank could be shipped doubledwithout havin its ends joined. our joined blank or box-tu is moremarketable than either an unjoined blank or a corner-joined one inA thatit saves to the customer the time and labor of joining the ends, besidesaffording a more. secure an extensive joint and one whose extremitiesare protected in the complete box, as nereinafter tinted out. Y

The c ove-tails or interlocking recesses and projections 23, 24, Whilenotindispensable to our invention, serve to strengthen the joint.against pulling apart, and since they are lo cated in a flat. panelunder the adhesive tape 25, we. prevent any springin of the yinterthcbox. The panels are marked Vo6 from locking members which woud tend touplock them or loosen the tape, as in certain causes it to oecu lessroom than a ullv exeach other and from the a s by crease-lines i meetingedges to form a secure joint. or

the plane of the inetaneesvrhere dereteiis here at a corner idiot with edierentiy-arrenged blank. These doveeiis eis@ resist strain in enel i3.'.tl better than 4corner dore-tails, y reason of their lying K entirelywithin said piene.

it is of course not esscntiai that the ioint `'shall come exactly in themiddle of the f panel ia. i4.. 1o

When the fiat. tube reaches the user and is to ,be formed into a box, itis opened out into a rectangular tube end one or' the ends ris reversedas shown in Fig. tend is then ready to receive its contents through theo enl top end, the weight. of said contents, if

ey are of a heavy character, serving to hold the adherentJ bottom a, .sunder ressureend after the box has een lle the top iaV s may be closedin the seme manner as the ottoni flaps, that is by first bending in thejointed flap 19, 20 carrying the end of tape 25, and its opposite flap17, applying adhesive material if desired, and then bending in the othertia )s 16, 1S. This coiniletes the closure of t e box. and the top undottoni joints may if desired be perfected by covering them with pastedstrips 2G of paper or cloth.

Fi 6 shows a blank of the same form as in Flg. l, without the dove-tailinterlocking members. and this blank may be made up into a tube and theninto a box in the manner above-described.

le *M A e A W'e do not claim novelty for the blank shown 1n Fig. 6 as ithas been proposed i to use a blank of this general form, but folded in adilerentmanner, so that the top 'well ermed by the part-panels and theperoeps, wmcn are teit open or enjoined until the box is filled. This ofcourse ren t' I ders :mgirectieeble the use of oor improved form ofjoint and the method o melting it. @er invention possesses theadvantages, among others, that the blank can be parielly closed to forme tube es described, the K. l

gioint of 'which may taped to make e. strong union before being sentout. by the menueetorer, and our box furthermore does not require anyjig or form in setting it up i to be filled.

We cleinn- .1. A collapsed tubular paper box, made from e blanleseoredto form side panels and slit to form top and bottom -aps, the :loint ofsaid tube being on a line intermediate one of the side panels and theadjacent flaps, the :deps of said blank being adapted to be bent over toform the top and bottom walls,

and a nested strip covering the joint-linc across t e jointed panel andaps and leaving the a is free to be folded or unfolded.

2. A co apsed tubular :iper box, ,made from a blank scored vto orm sidepanels and slit to form top and bottom flaps, the

joint. of said tube being on a line interme- .diate one of the sidepanels and the adjacent flaps, the meeting edges of the said jointbeineP provided with interlockin dovetailed mem ers, the flaps of saidbunk being adapted to be bent over to fol-m the top and bottom walls.and a pasted strip covering the joint line across the jointed panel andflaps and leaving the ilapsfree to be folded or unfolded.

In testimony whereof we have hereunto set our hands in the presence oftwo snb- I scribing witnesses, this second day of Muy GEORGE W. GAIR.
